[1] Guggenheim Partners Investment Management, LLC, also known as Guggenheim Investments (the “Investment Manager”), has contractually agreed through February 1, 2027 to waive fees and/or reimburse expenses to the extent necessary to limit the ordinary operating expenses (including distribution (12b-1) fees (if any), but exclusive of brokerage costs, dividends on securities sold short, acquired fund fees and expenses, interest, taxes, litigation, indemnification, and extraordinary expenses) (“Operating Expenses”) of the Fund to the annual percentage of average daily net assets for each class of shares as follows: Class A-0.76%, Class C-1.51%, Institutional Class-0.51%, and Class P-0.76%. The Investment Manager is entitled to reimbursement by the Fund of fees waived or expenses reimbursed during any of the previous 36 months beginning on the date of the expense limitation agreement, provided that the Operating Expenses do not exceed the then-applicable expense cap. The agreement will expire when it reaches its termination or when the Investment Manager ceases to serve as such and it can be terminated by the Fund’s Board of Trustees, with certain waived fees and reimbursed expenses subject to the recoupment rights of the Investment Manager.
